UNITED ST TES PATENT OFFIC GUSTAVUS A. JASPER, OF GHARLESTOVVN, MAgSACHUSETTS.

IMPROVED MACHINE FOR CRUSHING SUGAR AND FORMING IT INTO BLOCKS.

Specification forming part of Letters Patent No. 40,043, dated September 22, 1863.

To all whom it may concern:

Be it known that I, GUSTAVUS A. JASPER, a resident of Oharlestown, in the county of Middlesex and State of Massachusetts, have invented a new and useful or Improved Machine for Crushing and Blocking Sugar; and I do hereby declare the same to be fully described in the following specification and rep: resented in the accompanying drawings, of which-' Figure 1 is a top view, Fig. 2 a front elevation, and Fig. 3 a longitudinal and vertical section, of the same.

The nature of my invention consists in a combination and arrangement, as hereinafter specified, of a rotary shaft and knives, one or more sets of stationary knives, and two rotary molding-cylinders, the latter being made with molding-cutters or devices arranged so as to co-operate substantially as hereinafter described.

In the drawings, A is a rotary shaft or cylinder, provided with one or more or several series of knives projecting radially from its periphery, and so arranged with respect to the knives b b b of one or more series of stationary knives as to pass between them while the shaft A may be in revolution, the said rotary knives and stationary knives, by co-operatingtogether, serving to cut up and break and more or less comminute loaves or large lumps of refined sugar after they may have been thrown into the upper part of the machine. The stationary knives b, above mentioned, of each series thereof project from a bar, 13, ar ranged parallel to the shaft A, and supported in position by a casing, 0, within, and sus tained by which the working parts of the machine are placed as shown in the drawings. Underneath the series of stationary knives and the breaking cylinder or shaft A and its knives there are two molding-cylinders, DD, whose axes are in one horizontal plane, and are parallel to that of the shaft A. The arrangement of the two molding-cylinders with respect to the mechanism over them is such as to cause the sugar, as fast as it may be broken up or crushed by the moving and stationary knives, to fall directly into the space be tween the upper halves of such two molding cylinders. On the shaft of each molding-cylinder there is a gear, e, one gear being of the same size as the other and engaging with it. Furthermore, one of the gears, by means of an intermediate gear, f, engages with a gear, fixed on the shaft From the above it will be seen that when either of the moldingcylinders is put in revolution in the direction of the arrow marked thereon it will not only revolve the other molding-cylinder in an opposite direction, but at the same time produce rotary motion of the shaft A and its knives in a direction denoted in Fig. 3 by the arrow h.

In the construction of each molding-cylinder there projects from its external curved surface a series of thin bars or plates, iii, they being arranged radially with respect to the axis of the cylinder and parallel to one another, and at equal distances asunder. At right angles tothese plates there is placed around each cylinder certain annular ribs, in k k, which interlock with the plates 1', and so as to form with them square and tapering recesses or molds Z Z Z. There-are the same number of recesses in one cylinder that there are in the other, and those of the two are so arranged that while the cylinders are in revolution a mold of one of them shall co-operate with a mold of the other in the formation of a block of sugar. During the revolution of the two molding-cylinders each range of molds is rolled in contact or cooperates with one of the ranges of molds of the other cylinder,

these several ranges being made to cooperate in succession in such manner as to compress the sugar and form it into blocks of a cubical form or an approximation thereto, the said blocks being discharged from the molds by the draft which the mold of one cylinder has away from its fellow mold of the other after each block may have been formed by their joint action.

WVhat I claim as my invention is The above-described improved sugar crushing and blocking machine having its parts arranged and constructed substantially in manner and to operate as specified.
